Combine equations (9.1) and (9.2) in order to solve for e/m in terms of V (the voltage that accelerates the electrons), B (the magnetic field produced by the Helmholtz coils) and r (the radius of the circular electron beam). Hint: the first iteration of this calculation usually ends up with functions of e/m on both sides. To achieve the final result, e/m = some function of V, B and r, you'll need to do some algebra.

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
